📝 Blog Post: How to Add a Tooltip to a User-Defined Function in Excel 2007

Have you ever wondered how to add a fancy tooltip to your own user-defined functions in Excel 2007, just like the built-in functions have? You know, when you start typing a function invocation, and Excel displays a helpful description and parameter list. Well, you're in luck! In this guide, we'll explore the common issues surrounding this question and provide easy solutions to achieve this tooltip magic. So, let's dive in! 💫

The Problem: Missing Tooltip for User-Defined Functions

You might have already noticed that Excel doesn't provide any direct method for adding tooltips to user-defined functions. Going through VBA Help, MSDN, and Excel and VBA forums might leave you empty-handed. But fear not, my friend! We're about to reveal a workaround that will make your user-defined functions shine with descriptive tooltips. 🎉

The Solution: Creating a Custom Function with a Tooltip

The trick to achieving the desired tooltip effect lies in using a hidden worksheet that contains the necessary information for the tooltip. Here's a step-by-step guide to help you get started:

1. Open your Excel workbook and navigate to the worksheet where you want to add the tooltip for your user-defined function.

2. Insert a new worksheet by right-clicking on an existing sheet tab and selecting "Insert."

3. Rename the newly created worksheet to something like "Tooltips" to keep things organized.

4. In the "Tooltips" worksheet, enter the names of your user-defined functions in column A.

5. In column B, provide a brief description of each function as you would like it to appear in the tooltip.

6. On the "Formulas" tab, click on "Name Manager" in the "Defined Names" group.

7. In the "Name Manager" dialog box, click on "New" to create a new named range.

8. Assign a name to the range, such as "TooltipsList," and set the "Refers to" field to the range of cells containing your function names in the "Tooltips" worksheet.

9. Close the "Name Manager" dialog box.

10. Now, it's time to modify your user-defined functions. In the VBA editor, locate the module containing your functions.

11. Add the following code at the beginning of each function definition:

Application.MacroOptions _
    Macro:=Application.Caller, _
    Description:=WorksheetFunction.VLookup(Application.Caller, _
    Worksheets("Tooltips").Range("TooltipsList"), 2, False)

1. Save your VBA project and close the VBA editor.

2. Try it out! In any cell, start typing your user-defined function, and marvel as the tooltip with the function's description appears just like the built-in functions. 🎩✨
